PNEUMATIC CASH-CARRIER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 411,334, dated September 17, 1889.

. Application filed May 9, 1889- Serial No. 310,118. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN L. GIVEN, of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Pneumatic Cash-Carrier Apparatus, of which the following is a full, clear, and exact description.

This invention consists of the combination, with apneumatic tube for the transmission of a carrier or other article therethrough, of certain construction and arrangement of parts at the delivery end of such pneumatic tube, so that the carrier or other article transmitted through the tube will be automatically delivered therefrom at such delivery end and with comparatively little force, all substantially as hereinafter fully described, reference being had to the accompanying sheets of drawings, in which- Figure 1 represents the present invention in front view; Fig. 2, a side elevation; Fig. 3, a side elevation showing change of position of one of the parts, Figs. 4 and 5, longitudinal central sections on line 4 4,Fi '.1, showing the operating parts in two different positions, to be hereinafter referred to; Fig. 6, a detail longitudinal central section on line 6 6, Fig. 2; Fig. 7, a cross-section on line 7 '7, Fig. 6; and Fig. 8, a cross-section, enlarged, on line 8 8, Fig. 5. Fig. 9 is a detail side View of some of the parts, Figs. 4, 5, 6, 7, and 8 being enlarged. Fig. 10 is a detail sectional view to be hereinafter referred to. Fig. 11 is a longitudinal section on line 6 6, Fig. 2, to be hereinafter referred to.

In the drawings, A represents the end of a pneumatic tube for the transmission of a carrier or other article therethrough, and secured by a screw-thread in the lower end of a standard B, secured in any suitable manner to the table or stand 0. This standard B is in tube form and makes practieallya continuation of the pneumatic or main tube A, and has an opening D in the front for the delivery of the carrier or other article thereat, and to facilitate such delivery the standard is secured in an inclined. or angular position to the table, with its delivery-opening on its under or front side, as shown in the drawings. The upper end of the standard has a cap E, which screws onto a sleeve or coupling F, which sleeve in turn screws into the upper end of the standard, as shown in section in Figs. 4, 5, and 6 more particularly. This cap surrounds the upper part of the sleeve, leaving a chamber G around and above it, as shown. Screwing into the side of this cap E at a is an elbow II, having the end of a pneumatic tube J secured thereto by a screwthread, all as shown more particularly in Fig. Q.

The tube A is the portion of the main tube for the delivery of the carrier or other article at the station where the standard is, and the tube J is the portion of the main tube making the return-tube for the sending of a carrier or other article therethrough from the station where the standard is placed back to the station from which it came, or for com munication with the air-exhaust apparatus for the proper exhaustion of air in the tube for the transmission of the carrier or other article; but when used as a tube by which to return or to send a carrier therethrough it is provided with an opening K, arranged tobe covered with a gate or valve L, pivoted at b thereto. This return-tube can be inclined in the same direction as the standard, as shown in Figs. 1 and 2, or it can be in a vertical position, as shown in Fig. 3, the working of this return-tube not requiring any special angle of inclination.

M is a short tube within the standard, open from end to end, its exterior diameter somewhat less than the internal diameter of the standard to leave a space ("Z around the same between it and the standard, and having on each end an enlarged portion or flange N, each of which flanges closely fits the internal diameter of the standard sufficient to practieally prevent air from passing between the two, and yet loosely enough for the tube ill to slide freely up and down within the standard.

lVhen this sliding tube M is down in its norbelow thisend large openings P are made in its side, as shown in cross-section, Fig. 7, (in the present instance four in number,) making free communication for air between the interior of the sleeve and standard and the chamber G, made by the cap around and above the sleeve, which chamber has free communication with the return-tube J by a passage h in the side leading from said chamber to said return-tube, as shown in cross-section in Fig. 6, so that when the sliding tube M is in its normal position, as shown in Fig. 4, air can pass then through the sliding tube M up and out at the sleeve-openings P into the capchamber G, and into the return-tube to the airexhausting apparatus; but when the sliding tube is moved up into the position shown in Fig. 5, abutting against the upper closed end g of the sleeve, its upper end flange will then be above the bottom of the sleeve-openings, leaving a portion of each open and free for air to pass through, and its lower end flange below the upper end f of the delivery-opening D, so that air can then freely pass in at the delivery-opening at on (see Fig. 5) between the sliding tube and the standard and out at the sleeve-openings into the cap-chamber, and thence to the return-tube to air-exhaust.

The sliding tube and its operation in rela-' tion to the delivery-opening and the carrier are substantially the same as described and shown in Letters Patent 01": the United States issued to me dated March 20, 1888, and numbered 379,890, and needing no particular de scription herein; but the operation of the present sliding tube in connection with the other parts of this invention is as follows: The standard is placed at the station where it is desired to deliver the carrier or other article and in the inclined position shown, and the pneumatic tubes for the transmission of the carrier therethrough are properly conneoted therewith and the air-exhaust apparatus for the exhaustion of air in the direction of the arrows, Figs. 4, 5, and 6 more particularly, and as a carrier Q coming along the tube A, from the effect of exhausting air in front of it, reaches and makes a union with the open lower end of the sliding tube M, as shown in Fig. 4, it closes such opening to the passage of air therethrough, when the sliding tube then moves with the carrier upward until it strikes against the sleeve-head 9, closing the upper end of the sliding tube to the passage of air through it, so that air then freely passes in at the delivery-opening D and between the standard and tube and out at the sleeve-openings intothe chamber G, andthence to the return-tube, and to the air-exhaust apparatus, consequently relieving the pressure of air upon the carrier, which releases its hold with the sliding tube, from which it tube to the delivery-opening of another car rier or other article or of the return of the same by the return-tube. The return of the carrier is accomplished by opening the valve or gate of the return-tube and placing it in the opening leading thereto, its pointed end a down, and then, closing the valve, it is transmitted along the return-tube to the station from which it came by the air-exhausting apparatus.

In the manufacture of the apparatus it is preferable to make the standard of cast-iron, the pneumatic tubes being made of metal 111 the usual way of making tubes, and in lieu of having the sleeve it can be dispensed with and the cap be secured to the standard directly over its upper end, which can be closed in any suitable manner, and have the side openings P, for the operation, as before, and substantially as shown in detail in cross-section in Fig. 10, in which the standard-tube has its upper end at 0 closed and the openings P in its side and opening into the chamber G, formed by the cap E, secured over the end to the outside of the standard by a screw-thread, as shown in said figure.

The space or chamber R above the side openings P in the tube or standard, as shown more particularly in Fig. 11, confines the air therein, so that when the upper end of the sliding tube, with the carrier in union with its lower end, has passed above the side openings P the air in such chamber R and in the sliding tube will be more or less compressed and make a cushion for the sliding tube and carrier, causing a resistance to the movements of the same and aiding somewhat in releasing the carrier from its union with the sliding tube for its discharge at the delivery-opening, so that with the entrance of air at the delivery-openin g the carrier will be practically relieved of momentum and be delivered with a slight degree of force.

To prevent wear as the sliding tube strikes the head of the sleeve or the upper end of the tube A, the inner side of the sleeve-head has secured to it a piece 25 of soft yielding materialsuch as leatherand the upper end of the tube A has a piece a of similar material.

The standard is inclined, so that the carrier, after being relieved of its hold upon the sliding tube,will,as it drops therefrom by its gravity, fall out of the standard onto the table, while the incline of the standard for such purpose is not so much but that the sliding tube, after the carrier has ceased its connection therewith, will by its gravity return to its normal position and close the delivery-openin Such incline, it is preferable, should be about sixty degrees, although it can be of any angle that will accomplish the result desired. It can also incline sidewise or in any direction.

Having thus described my invention, whatl claim is 1. The combination, with a pneumatic tube for the transmission of a carrier therethrough, provided with an opening for the delivery thereat of the carrier, having its end closed and provided with side openings, leaving a space or chamber in said tube between the closed end and side openings, of a chamber surrounding the end of said pneumatic tube, having communication therewith through the side openings, and with a tube leading therefrom to the air-exl1aust apparatus, for the purpose specified.
